Models 1004 and 1014 photodetectors make ultra high-speed measurements easy. Their self-contained modules connect directly to test instruments like digital oscilloscopes, spectrum analyzers, and network analyzers for lightwave time- and frequency-domain measurements. They accept single-mode FC-fiber-optic inputs from your optical apparatus, eliminating the need for lossy and dispersive high-frequency coaxial cables. The internal housing of the high-speed models is specially designed to preserve the frequency response and phase to give true fidelity in your measurements.
These ultrahigh-speed photodetectors show flat response up to 45 GHz and are optimized for frequency-domain applications. For time-domain applications, we recommend our 12-ps photodetectors.
The photodiodes are powered by an easily accessible 9-V battery. The photodiode bias circuit and battery are housed in an RF-shielded case, reducing the risk of damage from excessive voltage or rough handling, and eliminating the need for expensive bias tees. All photodetectors also come equipped with a DC-bias monitor that has a transimpedance gain of 1 mV/µA and a 50-kHz bandwidth. Every photodetector is individually tested and shipped with its own frequency-response curve.
Applications
- Characterizing the frequency response of pulsed lasers, modulators, transmitters, and other lightwave components
